Since many high-end SSDs these days are bottlenecked by a PCIe 3.0 x4 interface, next-generation drives featuring a PCIe 4.0 x4 connector were among the highlights of this year’s Computex. Being one of Phison’s well-known partners, PNY showcased its upcoming XLR8 CS4040 SSD with a PCIe 4.0 x4 interface at the trade show.

PNY’s high-end XLR8 CS4040 SSD is based on Phison’s turnkey PS5016-E16 platform with 3D TLC NAND and will be available in 500 GB, 1 TB, and 2 TB versions. At present, PNY expects the drive to offer up to 4800 MB/s sequential read speed as well as up to 4000 MB/s sequential write speed in case of 1 TB and 2 TB models as well as up to 2100 MB/s sequential write speed in case of 500 GB SKU.

There is a need of high speed NVME ssds for more intensive data read and writes and with the launch of new X570 series, well, these SSDs have come to play an important role in data industry. Insane speeds are required in most cases and these SSDs serve the purpose really well.

Based on vague comments by the PNY rep we talked to about availability time frame of the drive and knowing PNY’s inclination to firmware tweaking, we are not quite sure that the company will be the among the first to launch its PCIe 4.0 x4 SSD when the first PCIe 4.0 platforms hit the market this July. In fact, we would expect the company to take its time and do some tweaking. But as the launch of this PNY SSD is expected soon, for the time being we do not know the exact date when it is going to be launched.

At Computex, PNY demonstrated its XLR8 CS4040 SSD with a very simplistic sticker that can barely be an efficient heat spreader. As Phison’s PS5012-E12 and PS5016-E16 controllers have a TDP of up to 8 W, a proper heatsink might be needed to guarantee consistent performance. That said, we can only wonder whether PNY installs a heat spreader on its XLR8 CS4040 SSD to maximize performance under high loads, or goes with a sticker to maintain compatibility with existing and future notebooks.

This is all the information we collected from computex this year. The only thing is, we do not know the exact date when this SSD will hit the market but it is pretty sure that PNY is making one as it was showcased in Computex 2019.
